The Insignia's refresh also brings a change in trims, with ES and Exclusiv replaced by a single Design trim. All models now come with LED daytime running lights, 16-inch alloys, Bluetooth and DAB radio as standard.

Vauxhall's reduction of the Insignia's list price means a drop in the P11D value, which will result in company car drivers paying less benefit in kind (BIK) tax.

The cut in CO2 emissions will also add to savings in BIK payments. The 2.0-litre CDTi Ecoflex is available in 118bhp and 138bhp variants. These core fleet models both emit just 99g/km of CO2, which is down from the outgoing 128bhp engine's 112g/km.

This brings a drop of three BIK tax bands, cutting the driver's contribution from 17% to 14%.

For example, a 2.0 CDTi 120 Ecoflex Design with a P11D value of £18,690 will cost a 40% taxpayer £87.22 a month in BIK tax, whereas the outgoing £22,195 2.0 CDTi 130 Ecoflex Exclusiv would incur a £125.77 monthly bill.
